You were the princess. The daughter of a very strict king. But you fell in love with a commoner. And when your dad found out, he sent him out to the sea to keep him away from you.

Moments before the ship was going, you asked him: "come back..." He looked at you with a reassuring smile. "I will." And then got on the ship.

Many years later, your dad has already wed you to a prince. But, he kept his promise. Kian came back.
